Neutrinos, WMAP, and BBN
Lawrence M. Krauss, Cecilia Lunardini, Christel Smith
New data from WMAP have appeared, related to both the fractional energy density in relativistic species at decoupling and also the primordial helium abundance, at the same time as…
Nuclear weak interaction rates in primordial nucleosynthesis
George M. Fuller, Christel J. Smith
We calculate the weak interaction rates of selected light nuclei during the epoch of Big Bang Nucleosynthesis (BBN), and we assess the impact of these rates on nuclear abundance fl…
New Nuclear Physics for Big Bang Nucleosynthesis
Richard N. Boyd, Carl R. Brune, George M. Fuller +1
We discuss nuclear reactions which could play a role in Big Bang Nucleosynthesis (BBN). Most of these reactions involve lithium and beryllium isotopes and the rates for some of the…
Using Big Bang Nucleosynthesis to Extend CMB Probes of Neutrino Physics
M. Shimon, N. J. Miller, C. T. Kishimoto +3
We present calculations showing that upcoming Cosmic Microwave Background (CMB) experiments will have the power to improve on current constraints on neutrino masses and provide new…
Weak Interaction Rate Coulomb Corrections in Big Bang Nucleosynthesis
Christel J. Smith, George M. Fuller
We have applied a fully relativistic Coulomb wave correction to the weak reactions in the full Kawano/Wagoner Big Bang Nucleosynthesis (BBN) code. We have also added the zero tempe…
Big Bang Nucleosynthesis with Independent Neutrino Distribution Functions
Christel J. Smith, George M. Fuller, Michael S. Smith
We have performed new Big Bang Nucleosynthesis calculations which employ arbitrarily-specified, time-dependent neutrino and antineutrino distribution functions for each of up to fo…
Light Element Signatures of Sterile Neutrinos and Cosmological Lepton Numbers
Christel J. Smith, George M. Fuller, Chad T. Kishimoto +1
We study primordial nucleosynthesis abundance yields for assumed ranges of cosmological lepton numbers, sterile neutrino mass-squared differences and active-sterile vacuum mixing a…
Coherent Active-Sterile Neutrino Flavor Transformation in the Early Universe
Chad T. Kishimoto, George M. Fuller, Christel J. Smith
We solve the problem of coherent Mikheyev-Smirnov-Wolfenstein (MSW) resonant active-to-sterile neutrino flavor conversion driven by an initial lepton number in the early universe.…
Are B to PI K CP-asymmetries quantized ?
Jean-Marc Gerard, Christopher Smith
Search for patterns in the numerous B-decay modes now available is necessary in order to test the Cabibbo-Kobayashi-Maskawa theory of CP-violation. In particular, the well-structur…
